SHAPER GUZDE.

Application filed December l., 19752.

To m7] unioni it iimy/ concern Be it known that l, JOHN J. Ruine a citi- Zen oit the United States` residing' Grand Haven in the county oit (lttaw-i and State of lilichigran` have invented certai new and useful lmprovenieutsin Shaper Guides` ot which the Jfollmvintr is s. specification,

My invention relates to improvements in guides for sluiping;f articlesV upon a power Shaper, particularly for shaping toiletv seats, and its objects are: first; to provide a means whereby the operator mayhave a clear view et his worlr without danger of having his eyes filled with dust etc.; second, to provide a means wherein7 the seats may he \I\1 readily and accurately clamped into the guide; thirdq to provide a means'wherebv the openings in the seats may be properly shaped with less expenditure of time and labor than is necessary with ordinary guides. and` fourth. to provide a means whereby the seats to be. shaped may be readily and easily clamped upon, and removed from the guide.

l attain these obiects by the mechanism and construction of parts shown in the accompanying' drawing` in which Fig. 1 is an elevation of the guide complete. Fitz. 2 is a sectional elevation of the saine. Fig. 3 is a top plan.` and Fig. 4 is a bottom plan of the saine. Fig. 5 shows the position' ot' the ,guide when inserting' a seat therein, and Fie. 6 is an edge elevation of the same.

Similar numerals indicate similar parts throughout the several views.

in the construction of this guide'lf malte a base 1-1 having an opening 15 through the part 1 and a like opening through the part 1. except that the opening through the part 1 has an odset 16 therein designed to carry the seat material a little further Jtrom the knives 27 at the front, and malte the curvature of the surface of the material a tride more abrupt than at the sides and back, as indicated at b.. compared with the form at @e in Fig. 2. the edges oi' the openiner 15 being: designed as a guide for the roller 19 to travel upon for shaping the ed s a-b of the seat. The roller 19 is designed to be made adiustables or slidable upon the shaft 17 Aas indicated by the solid and the dotted lines in Fig. 2 so as to change the forni of the shaping if desired Serial No. $134,297.

For `clamping the seat pattern into the guide l place sharp spurs 13, into the bacs supporting rail 5 designed to enter the edge ot the seat 12, as indicated in Figs 1 and 2, and at the other end ott-he. guide l place a. retaining lever il having an`engaginuy spur 7 designed to be forced into the edge of the seat by means of the screw 10 working through the support 9, and operated by the crank 10.y the lever 7 being pivotally ccnnected with the hinge 6'D as at 3, in such a manner that when the point or spur 7 is forced into the edge of the material to be shaped it will have a tendency to draw the material against the lower surface of the base 1, 1 suiicieutly to avert any danger of the sli ghest vertical movement or trembling of the material when being acted upon by the Shaper knives. l, also, place an actuating spring 11 in the base or bed 1, 1 in position to force the spur out of contact with the cover when the lever 7 is released from the pressure ot the screw 10. When the seat 12 has been properly clamped upon the guide base 1 the seat is placed with its eX- posed surface upon' the upper surface of the Shaper bed 14C` with the roller 19 bearing upon the surface of the inner edge ot the 2duide to enable the. operator to hold the worlr., tirrnly against the revolving knives 27 when beiner shaped.

At 5 l' have shown an upwardly extend ingr bearing designed to act as a support to hold the guide in vertical position when iusertingr or removing a, cover, and 4. 4; represent standards or handles by means ot which the operater may hold and guide the implenient as desired. and by means of which the guide may be held iirmly to the work when shaping the inner and upper surface of the seat.

25 represents an opening through the bed 14T ot the Shaper traine through which the shavings Jfrom the Shaper knives 27 are made to pass into the receiver 23, whence they are forced through the pipe 24 by means of an appropriate blower fan, not here shown as it has no direct connection with this invention.

For the purpose of providing a means whereby a perfect view may be had of the working parts of the machine without danger of dust, shavings, etc., being blown into the face and eyes of the operator, I forni a cylindrical chamber or donie 2 upon the upper surface of the part l of the guide and secure it by sonie available means for the purpose, as, for instance, by means of a securing ring 3 securely connected with the bed l and with the Walls of the deine 2. In the top of the doine 2 I place a. transparent cover, as of glass. Celluloid or kindred inaterial, as indicated at 20, which may be held securely in place by any of the usual means employed for sueh purposes, as, for instance, l' sometimes place a lining' plate Q2 inside of the deine Wall@ upon the edge of which the edge of the top 20 may be made to rest` and to hold the top in place an open eap or bor der '2l may be placed over'the edges of the top 2O and downwardljif over the upper end of the doine Wall, as indicated in Fig. 2. By this means, it will be readily understood that this transparent top, 20, may be left absolutely unobstructed, and with the blower carryingthe shavings and dust outfthrough the pipe 24, and the deine thoroughly enclosed with the transparent top 20,'it Will be possible to plainly see the operationof the Shaper knives Without the least danger of dust, etc., filling the 'atmosphere above the Shaper bed and greatly inconveniencing the.

operator, as is usual when the Work is left exposed, no matter how perfectly the blower niay be ope ating in carrying olf the shaviugs and dust from the machine.

26 represents an ordinary collar upon the shaft l? for holding this shaft in proper .'eitioal position in its retaining boxes. K

Having; thus fully described my invention, what "f claiin as new and desire'to'seeure by Letters Patent, is: Y e t i. In combination with a guide for shaping the openings in toilet seats, a forni body haying stationary spurs at one end for engaging the edge of the material to be shaped, au adjustable spur pivotally mounted above the edge of the base at the` other end and ei:- tending downwardly into position 'so' t Le points niay'be inade Vto 1genetrate'the edge of the material tog,besl1apcd and springv chanibered in the'base in positionto Vforce the spur out of engagement with the niaterial when' its pivotal body' is released, and escrow and rack' for forcing the spur into engagement with the material.

2. ln combination with the elements covered in claim l', a crib mounted' upon the base around thel openingtherethrough, and

an unobstructed transparentcover over said crib.
